Answer:
p=1
Step-by-step explanation:
5(p+3)=18+2p
5p+15=18+2p
5p-2p=18-15
3p=3
p=<u>3</u>
3
p=1
Answer:
(x + 5) /2
Step-by-step explanation:
"a number" (this will represent as "x")
"increased" another way to say add or "+"
then divided by 2
If you wrote it out like this "x+5/2"it would be wrong because of PEMDAS making you want to divide first instead of after.
Answer:
<h3> 78%</h3>
Step-by-step explanation:
Given
Number of scientist that line in Antarctica during the winter = 1,100
Amount of scientist in the summer = 5,000
Increment = 5000 - 1100
Increment = 3900
percentage change = Increment/Original amount * 100
Percentage change = 3900/5000 * 100
Percentage change = 3900/50
Percentage change = 78%
<em>Hence the percent change in the number of scientists living in Antarctica is 78%</em>
Answer:
4)2.4
Step-by-step explanation:
-1.5 ( -3.6 + 2 )
To solve this problem, we apply PEMDAS.
This is the order of operation for mathematical problems.
P Parentheses
E Exponent
M Multiplication
D Division
A Addition
S Subtraction
-1.5 ( -3.6 + 2 )
Do the problem in the parentheses first,
= -1.5 x (-1.6)
= 2.4
Answer:
The only difference is that 2 uses "f" and 3 uses "g". You solve them the same way and everything, but the variable is just different
